Well a 25% increase would only bring you up to 12.5Mb/s
That's way to much extra for what you get, I just tested a 1Gb/s line on seedmybox and the fastest speed I recorded was 50Mb/s down and 20Mb/s up.
Gold plan

$25.99/month
Unlimited Active torrents
110 GB Disk space

The storage is small but with those speeds I wouldn't care, all plans are set up with admin control panel, Rapidleech and irssi Auto DL installed.
I don't think these guys oversell.
